Hello everyone,
I just want to know if there is a difference in performance between using Class methods versus MAC routines?
For example:
do Method^MyFunction()
versus
do ##class(MyFunction).Method()

I'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:
I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.
HSCUSTOM>S file=##class(%Stream.FileCharacter).%New()
HSCUSTOM>Do file.LinkToFile("/data/binary.json")
HSCUSTOM>w file.When registering the components: I used this command:
"Utils.migrate("/external/src/CoreModel/Python/settings.py)" ;
The error appears: "An error has occurred: iris.cls: error finding class",
I changed with these two lines:
result = subprocess.run(["iop", "-m", "/external/src/CoreModel/Python/settings.py"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, check=True)
subprocess.run(["iop", "-m", "/external/src/CoreModel/Python/settings.py"], stdout=subprocess.DEVNULL, stderr=subprocess.
Hi
We have a use case whereby very large HL7 MDM messages, which contain many OBX segments, need to be processed by a custom business process. Part of the process is to iterate over each OBX segment and set a value in the same field for each segment.
Testing with a message that is ~500MB and contains over 8000 OBX segments I've encountered <STORE> errors, which surprisingly seems to be due to using SetValueAt. It appears to get through a few thousand segments before it falls over with the memory error, which I assume is because the SetValueAt method keeps in memory each preceding OBX segment?

Hi Team,
This is very urgent can you please guide me to convert the date string to ISO format.
set date = "20240501144800-0500"
set result = $SYSTEM.SQL.Functions.TOTIMESTAMP(date, "YYYYMMDDHHMISS")
write result -> 2024-05-01T16:49:00:00+00:00
so here timezone is dropped off but i need that.
expected result -> 2024-05-01T16:49:00-05:00
Please help me here how i can convert in this format.
Hello, Is there an equivelant to HS.FHIRServer.Tools.DataLoader.SubmitResourceFiles for bulk fhir data (.ndjson) that exists to import from a local directory in I4H ?
Hey,
I'm testing a REST API that is used for our IRIS Backend with a mobile app (Angular / ionic).
The problem is that, our test environment does not yet have HTTPS capabilities, it's something we're going to set up ASAP, but right now we don't have it set up.
We want to test the API endpoints via a web browser using either a test application built in Angular, or the app itself built with NPM via the browser. This means that the set-cookie headers are being blocked by the browser.
Is there a way that we can allow the set-cookie header to be set in the browser for testing?
Hello Community,
I've seen two cached queries are generated while executing a query. So, Why the additional query is generated and what is the use of it.

My team and I noticed that the %ZEN class documentation labeled all properties and methods as deprecated.
In this regard, the big question is: what will be used to replace these methods, in particular %ZEN.Auxiliary.altJSONProvider?
It is used as the basis for the MDX2JSON package, from which DeepSeeWeb gets data to build Analytical Dashboards.
Is a replacement proposed for deprecated methods of %ZEN class?
And when is this functionality scheduled to be permanently disabled?
Hello community,
I'd like to briefly announce three new packages, available on the Open Exchange / through ZPM, that can really help accelerate modern full-stack application development on IRIS. I announced all of these in a Global Summit session last week, but you may have missed it - and I hear there's a full-stack application development contest coming up!
At the heart of this is isc.rest: a continuation of apps-rest with broader use within InterSystems and some new killer features - most notably, OpenAPI spec generation. isc.

Hello community, first of all, apologies if anyone was offended by the blasphemy 😔
Have you ever thought it would be interesting to have the source code separated from the database data? Perhaps you'd like to be able to back up your code without copying gigabytes of client data.
Below, I'll explain the steps to separate your sea formed by the source code and data into two different databases within a
Hi Community!
Our 💡 3rd InterSystems Ideas Contest has come to an end. As a result, there are 🔥 30 new ideas! They all focus on improving InterSystems IRIS and related products and services, highlighting tangible benefits for developers once the ideas are implemented.
And now we announce the winners...
Good afternoon,
I'm trying to start an instance of the Community Edition with Docker and I get the following error.
I tried downloading the object-script template directly from OpenExchange, but one of these two things always happens:
1 - It gets stuck starting up forever
[+] Building 147.We have a stand-alone web platform (readysetrecover.com) that helps people prepare for surgery focusing on the non-clinical – holistic and logistic aspects (stress reduction via meditation, sleep etc. as well as things like setting up the house, coordinating help from others etc).
We had a meeting with a hospital, and they liked our solution but said their goal is ‘to provide patient education and communication on a single platform'. They currently use Epic and MyChart.
As of October 15, 2024, support for Caché & Ensemble on MacOS will be Deprecated.
Caché & Ensemble 2018.1.9 will continue to be supported, however there will be no further maintenance releases for MacOS. This means Caché & Ensemble 2018.1.9 will be the final version of these products on MacOS.
As a reminder, maintenance releases for Caché and Ensemble on the other supported platforms will come to an end on March 31, 2027. More details on that can be found in last year’s announcement.
We are constantly running into issues where there are billions of Orphaned messages in our system that cause problems, and we have to manually run a cleanup to fix performance issues.
In the following article about orphaned messages... https://community.intersystems.com/post/ensemble-orphaned-messages it mentions either programmatically eliminating the Orphaned messages or using a Utility like Demo.Util.CleanupSet in ENSDEMO.
I have had it explained to me is basically all messages have to go somewhere, if they aren't then it creates orphaned
Could any one tell me, how the index works in cache db, Consider for example, I have a table called "Employee" and the fields as "EMPID, EMPNAME, EMPAGE" and I am having index for EMPID as IDX_EMPID and trying to get the record using the following query as
SELECT * FROM EMPLOYEE WHERE EMPID="005"
and the table data be like
EMPID EMPNAME EMPAGE
001 ABC 20
002 AAA 21
003 ABB 23
004 BBB 20
005 BDF 24
006 EEE 22
Will SQL Engine directly hit the "005" record using ^EMPLOYEEI global, if so how it is happening,
Hi Community!
How can you create a balanced approach to using Generative AI? Get help from InterSystems experts in the latest video from Learning Services:
I have been using embedded python for more than 2 years now on a daily basis. May be it's time to share some feedback about this journey.
Why write this feedback? Because, I guess, I'm like most of the people here, an ObjectScript developer, and I think that the community would benefit from this feedback and could better understand the pros & cons of chosing embedded python for developing stuff in IRIS. And also avoid some pitfalls.

Is there a way to capture the SQL command that was sent to Cache ? I need to know how to do this. Any help would be appreciated. It is from an external application using JDBC or OBDC. Thanks

Has anyone had experience migrating source control projects from Subversion to Github, particularly when transitioning from InterSystems Studio to VSCode?
We have a requirement where in certain data from IRIS in almost real time has to join with SQL tables and we are trying to avoid linked servers.
Is there a way to achieve this without having to go through ODBC?
Hi
I get the following error when I am trying to create a linked server connection via MS OLE DB Provider for ODBC Drivers in MS SQL Server Management Studio. The message I get is:
The OLE DB provider "MSDASQL" for linked server "IRIS" reported an error. The provider did not give any information about the error.
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "IRIS". (Framework Microsoft SqlClient Data Provider)
I have setup the InterSystems ODBC setting on the server.
InterSystems Reports version 24.1 is now available from the InterSystems Software Distribution site in the Components section. The software is labeled InterSystems Reports Designer and InterSystems Reports Server and is available for Mac OSX, Windows and Linux operating systems.
This new release brings along some great enhancements from our partner, insightsoftware. InterSystems Reports 24.1 is powered by Logi Report Version 24.
Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure.
I tried using fromDao(dao As %DynamicAbstractObject) As <HS.FHIRModel.
